Orthophoto of the Czech Republic - Kamenice nad Lipou 6-7
收藏资源简介:
Digital seemingly seamless orthophoto of the Czech Republic in a 8-bit color scale. The pixel of the raster image Ortofota ČR displays 0.200 m (band „East), resp. 0.125 m ("West" zone) of the area in the middle plane of the terrain. The orthophoto of the Czech Republic is constantly improving its positional accuracy characterized by a mean positional error, this error ranged from 0.20 to 0.21 m in the years 2019 - 2020. The evaluation of the accuracy of the orthophoto of the Czech Republic in 2021 has not yet been completed. Orthofoto ČR is distributed in graphic raster formats JPG in dispensing units with a size showing 2.5 x 2 km of terrain in the SM 5 clade.
捷克共和国近乎无缝的数字正射影像图(orthophoto)采用8位色彩深度。该栅格影像Ortofota ČR的像素对应地形中平面的实地面积:东区波段的像素对应0.200米范围,西区波段则对应0.125米范围。捷克共和国正射影像图的位置精度持续提升,以平均位置误差为表征指标;2019至2020年间,该误差区间为0.20至0.21米。2021年捷克共和国正射影像图的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式进行分发,其分发单元的尺寸对应实地2.5×2公里范围,采用SM 5级分幅规格。
